Problems solved by technology
Previously, it was not easy to check the oil level in each compressor, so the oil return operation used to be done for a predetermined period of time regardless of the actual oil level
However, this may not be very effective in this case, as there is a possibility that the oil return operation will be forced even when the oil level is actually sufficient, and during the oil return operation, when no air cooling is provided. may consume energy
[0007] That is to say, the air conditioner cannot work as a cooling or heating system when performing the oil return operation, and the oil return operation at short intervals is ineffective consumption in terms of energy consumption and may increase inconvenience

Embodiment Construction
[0045] Hereinafter, an embodiment of an operating method of an air conditioner having a plurality of compressors according to the present invention will be described in detail with reference to the accompanying drawings.
[0046] figure 1 is a schematic diagram of an air conditioner with multiple compressors according to one embodiment. refer to figure 1 , the air conditioner may include a plurality of compressors 100, 100', 100", and these compressors may have the same structure. Each compressor may include a first suction pipe 110 through which refrigerant can flow, and from the first suction pipe 110 branch to the second suction pipe 112, 112', 112" of each respective compressor 100, 100', 100". In addition, each compressor 100, 100', 100" discharge compressed refrigerant.
[0047] Oil may be stored within the compressor, which may contribute to lower friction within the compressor during operation. Furthermore, an oil level detection sensor 102, 102', 102" for detectin...

An air conditioner and a method of operating the same are provided. The air conditioner may include a plurality of compressors (100,100',100''), each of which may include a casing that stores oil therein, and an oil level detecting device (102,102',102'') that detects an oil level within the casing. Once oil levels within each of the plurality of compressors are detected, oil may be redistributed between the plurality of compressors without interrupting a normal operation of the air conditioner. Oil may be transferred from a compressor having an oil level greater than a desired amount to a compressor having an oil level less than the desired amount. If there remains a compressor that contains an insufficient amount of oil after redistributing the oil among the plurality of compressors, an oil collecting operation may be performed.
Description
technical field [0001] The present application relates to an operating method of an air conditioner. Background technique [0002] Generally, the compressor is provided with a driving motor for generating a driving force in the internal space of the container, and a compression unit for compressing refrigerant while operating in cooperation with the driving motor. The compressor can be divided into reciprocating type, scroll type, rotary type and vibrating type according to how it compresses the refrigerant. Reciprocating, scroll, and rotary compressors are based on a method using the rotary motion of a drive motor, while vibratory compressors are based on a method using the reciprocating motion of a drive motor. [0003] The drive motor of the compressor using the rotary motion among the aforementioned compressors is provided with a crankshaft so that the rotary motion of the drive motor is transmitted to the compression unit. For example, a driving motor of a rotary comp...
